    I am afraid ther are just too many species many which I am not familiar. Each species is also extremely variable.

    Basically they can be divided into 2 main groups ;1. HW with yellow spots & 2. HW without yellow spots.

    1 HW with yellow spots.

    a, FW with a yellow or white sub-basal spot in space 1b ie. C. ambareesa, pulomaya ,pero, pyrrha & ratna.

    b. FW without a sub basal spot. C. leucocera, putra, plagifera, morene & patula.

    b1. FW with two spots in space 1b C. plagifera & morene.

    b2. FW with 1 spot in space 1b.

    C. patula HW with large yellow spots FW band not extending into costa.

    C. leucocera :HW with smaller spots FW band usually extend above radius (not always)FW band typically comprise of irregular large spots. Termen shorter than dorsum ;apex rounded & margin more convex.

    C. putra; HW with smaller spots; FW termen = dorsum; apex sharper & termen straighter. FW band composed of smaller spots usdually with straighter margins, not extending to costa but sometimes with a tiny spot above the radius.

    Your shots all look to be C. leucocera. The apex is not that sharp & the termen more rounded.

    TL Seow; Cheers.
